The possibility of improving the parameters of a reactive-power compensator operating in nonsinusoidal modes has been studied by means of supplementary assessment of the design power of the compensator. It is based on the decomposition of the instantaneous power into components in the modes of phase shift of current relative to supply voltage. The temporal distortion of the curve of current is also studied. To date, numerous attempts have been done to generalize the concept of reactive power to nonsinusoidal processes or to introduce other general concepts, but these attempts have not led to the creation of a generally accepted theory that would adequately reflect energetic processes in the general case in the presence of distortions of current and voltage. This paper aims to increase the efficiency of reactive power-compensator equipment for agricultural and industrial consumers operating in nonsinusoidal modes. This is achieved by the use of supplementary computational procedures in the controlling algorithm of a reactive-power compensator. In this case, the transmission-line resistance and internal resistance of the power supply are taken into account.
